Thread.new

Desktop wxRuby
1

This code runs fine (except you can’t mess with the window until the 10
loops are finished). But if the comment mark is moved down to the
10.times
do so that it can run in a different thread, nothing below Thread.new do
ever happens. Help! please. Thanks.

I’m running Ruby 1.9.3 and wxRuby 2.01.

def busy_task
# start task in a separate thread
@text.append_text “In busy_task\n”

Thread.new do

10.times do
  @text.append_text "In busy_task\n"
  @tasks += 1
  tasks = @tasks
  10.times do
    @text.append_text "running #{tasks} ... #{Time.new}\n"
    (1...1_00_000).inject :+
  end # do
  @text.append_text "Thread #{tasks} done\n"
end # do

end # busy_task

wxRuby doesn’t like threads. Search the mailing list archives and
you’ll find plenty of topics related to your problem. If you don’t
need shared memory, I recommend you to look into processes.
